What is the standard size of a 1U server chassis?

The length of 1U server chassis is divided into standard group and short group. The length of the "standard group" is about 625-725 mm, which can accommodate PC motherboards and dual CPU server motherboards (including 12×13 inches large size); "short group" "The length is about 360-525mm, which can only be used to install PC motherboards and single CPU server motherboards (the largest PC motherboards are no problem). The 1U server chassis of the “standard group” is suitable for the size of major domestic and foreign telecom-class chassis cabinets. The current standard cabinet depth of China Telecom’s computer room is 85cm-100cm. If your cabinet is not of standard depth and is relatively shallow, you can choose "short The 1U server chassis in the "Family Group" and the 1U server chassis in the short-term Group have better compatibility.OLT Device is one of the most commonly used fiber optic equipment, which is also known as network device and FTTB FTTX equipment. Among these, one of the most commonly seen is EPON OLT. EPON OLT usually have uplink port and downlink port which supports data transfer, which is very important to WEB management function of OLT.
